 Title: #706: KCM: Fall back to using the first ccache if the default does not exist
Action: opened

PR body:
"""
Resolves: https://pagure.io/SSSD/sssd/issue/3838

KCM stores the default ccache in a separate DB entry. If the DB entry 
contains a UUID that cannot be found in the DB for whatever reason, we 
should just use the first ccache as the default. (This is what we already
do if there is no default)
