control: Fix NULL pointer access in HS desc event
This was introduced 90562fc23a7ce61f3660b507d9991a27af2eae37 adding a code
path where we pass a NULL pointer for the HSDir fingerprint to the control
event subsystem. The HS desc failed function wasn't handling properly that
pointer for a NULL value.
Two unit tests are also added in this commit to make sure we handle properly
the case of a NULL hsdir fingerprint and a NULL content as well.
Fixes #22138
