fix(commit.py): filter merge request search to 'opened' and on current branch.

Merge request search now filters to 'opened' and to ones on the current branch.
if none were found, outputs 'ci: No Merge Request found, MR count "0"'

any other error with finding the merge request will output
'failed to fetch Merge Request title' this enables further debugging for
potential errors.
