When launching an electrum daemon and an electrum cli command quickly after each other,
in a test using a random fresh datadir, they both try to create the same folder hierarchy
and race on the "if not exist: mkdir" commands.

On Windows, above commit broke dns_hacks.py with dnspython==2.0.0 and 2.1.0.
Newer dnspython works.
Root cause not immediately obvious. Probably not worth debugging, I will just bump the required version instead.
With dnspython==2.0.0, the log gets spammed and dns fails:
```
$ python3 -m pip install --user "dnspython==2.0.0"

```
With dnspython==2.1.0, no more log spam but all dns resolutions time out:
```
$ python3 -m pip install --user "dnspython==2.1.0"

so we don't error out when GUI hinted minimum 2mBTC channel size is used for peers that
constrain max-htlc-in-flight to 45% of channel capacity. (fixes#8712)
fixes broken test_trampoline_mpp_consolidation caused to fail by
https://github.com/spesmilo/electrum/pull/9845 by allowing single
channel splits for trampoline payments if TEST_FORCE_MPP is Trues
as the test relies on mpp through a single channel (it tests mpp and
there is only a single channel on the graph).
introduces a class SwapOffer which is used instead of passing around
offers in dicts.
Also fixes incorrect variable naming of swapserver npubs / public keys
by assigning the npub instead of the hex pubkey to
config.SWAPSERVER_NPUB
