Main motivation is that I often use wallet.remove_transaction
from the Qt console, and would find this behaviour more intuitive.
Note that previously if one were to call this on a tx with children,
the crash reporter would appear with "wallet.get_history() failed balance sanity-check".

This was a regression from e83f0dd3fc,
introduced by the change in connection_down() there.
(if the initial connection to the main interface is not successful, the
network status will not be set to 'disconnected' - but it should be)
That change is now reverted here.
That change was somewhat independent of the rest of that commit,
except the rest highlighted that something of the sort was needed:
as it might sometimes take many seconds for an interface to close
and we might launch another interface for the same server while the
first one is still closing, the "server == self.default_server" test
is highly problematic.
To fix this second - original - issue, we now introduce a "closing" state
for interfaces (in the form of network._closing_ifaces).
When the app is started, the password is checked against all
wallets in the directory.
If the test passes:
- subsequent wallet creations will use the same password
- subsequent password updates will be performed on all wallets
- wallets that are not storage encrypted will encrypted
on the next password update (even if they are watching-only)
This behaviour is restricted on Android, with a 'single_password' config variable.
Wallet creation without password is disabled if single_password is set
Had to also bump ubuntu version 18.04->20.04,
as was getting errors running the self-compiled pyinstaller otherwise (weird...):
```
from .utils.git import get_repo_revision
ModuleNotFoundError: No module named 'PyInstaller.utils'
```
(similar to https://github.com/pyinstaller/pyinstaller/issues/4403 )

Note re appimage: when trying to compile python 3.8.x on ubuntu 16.04, I am getting:
./Modules/posixmodule.c: In function ‘os_copy_file_range_impl’:
./Modules/posixmodule.c:10351:15: error: implicit declaration of function ‘copy_file_range’ [-Werror=implicit-function-declaration]
ret = copy_file_range(src, p_offset_src, dst, p_offset_dst, count, flags);
This is because ubuntu 16.04 has too old glibc.
Upfront shutdown script is a script provided on channel opening,
which will be used by the peer to enforce us closing to this script
on collaborative channel close.
