Add federation tests for Friendica, improve parsing of source field

[Nutomic]

I love how easily this works now, seems like Lemmy is already very compatible.

I upgraded to 0.15.4 today and checked again...

The error still persists:

[dessalines]

data did not match any variant of untagged enum

I'd suggest opening up a new issue for this if one doesn't already exist.

Should it be fixed in 0.15.4?
@Nutomic wrote in matrix, i should wait a few days for 0.16...
