Caused by dirContains ".." "foo" being incorrectly False.
Also added a test of dirContains, which includes all the previous bug fixes
I could find and some obvious cases.

Fix bug that caused stale git-annex branch information to read when
annex.private or remote.name.annex-private is set.
The private journal file should not prevent reading more current
information from the git-annex branch, but used to.
Note that, overBranchFileContents has to do additional work now, when
there's a private journal file, it reads from the branch redundantly
and more slowly.

This is a potentially breaking change in a very delicate area. However,
examining the code path for writes, I don't see any benefit to opening a
second db connection for them. If the write throws an exception,
commitDb will retry it with a new db connection.
A potential benefit to not opening a second db connection, beyond using
less resources, is it just might avoid problems in WSL with sqlite that
I have hypothesized are caused by multiple db connections.
Commit 5f9eff3f32 explains why it needs to
shut down the db connection to force the database to be updated on disk:
When closeDb does not get called, garbage collection of DbHandle may not
give the workterThread time to cleanly shut down before git-annex exits,
resulting in a recently written change not reaching disk.
After commit f4bdecc4ec, there is no
longer any distinction between SingleWriter and MultiWriter's handling
of read after write.
Databases that were SingleWriter still have lock files that are used to
prevent multiple writers.
This does make writing to such databases a bit more expensive,
because the MultiWriter code path that is now used opens a second db
connection in order to write to them.
