findmissing: initdb_upstream: Record merges as handled

While we don't want to do anything with merges, we should still record
them as handled to avoid unnecessary non-linearities and thus duplicates
when traversing the list of commits again later on.

While at it, add space between error number and error text after
database errors to improve readability.

BUG=None
TEST=Run on GCE
