update tswg- to kswg-, bump keri to 1.2.12, fix quoting bug, and stabilize tests

[kentbull]

In addition to the tswg- to kswg- change I fixed a few things and upgraded KERIpy to 1.2.12.

• got test coverage back up to 100%
• quoting was broken on a corner case where no AID was present when a percent-encoding of a port was not in a did:webs DID. This would occur when using the default port of 80 or 443 if someone submitted an invalid DID. Just something I noticed.
• Some of the tests were unstable like the test_habs.py tests so I fixed them.
• various other small things to get the test coverage back up to 100%
