It seems we have never tested the case that restore --accumulate
actually adds tags. I noticed this when I started optimizing and no
tests failed.
The bracketing with "restore --input=dump.expected" are to make sure
we start in a known state, and we leave the database in a known state
for the next test.

# notmuch restore currently only considers the first argument.
