services: in loadOneBranch, return if CountDivergingCommits fail
If we can't count the number of diverging commits for one reason or
another (such as the branch being in the database, but missing from
disk), rather than logging an error and continuing into a crash (because
`divergence` will be nil), return an error instead.

services: Gracefully handle missing branches
When loading branches, if loading one fails, log an error, and ignore
the branch, rather than returning and causing an internal server error.
Ideally, we would only ignore the error if it was caused by a missing
branch, and do it silently, like the respective API endpoint does.
However, veryfing that at this place is not very practical, so for the
time being, ignore any and all branch loading errors.

tests: Add a testcase for missing branches
This tests the scenario reported in Codeberg/Community#1408: a branch
that is recorded in the database, but missing on disk was causing
internal server errors. With recent changes, that is no longer the case,
the error is logged and then ignored.
This test case tests this behaviour, that the repo's branches page on
the web UI functions even if the git branch is missing.

tests: More testing in TestDatabaseMissingABranch
In the `TestDatabaseMissingABranch` testcase, make sure that the
branches are in sync between the db and git before deleting a branch via
git, then compare the branch count from the web UI, making sure that it
returns an out-of-sync value first, and the correct one after another
sync.
This is currently tested by scraping the UI, and relies on the fact that
the branch counter is out of date before syncing. If that issue gets
resolved, we'll have to adjust the test to verify the sync another way.
