Prompted by the test suite on windows failing to with "export foo failed"
and no information about what went wrong.
Note that only storeExportWithContentIdentifier has been converted.
storeExport still returns a Bool and so exceptions may be hidden.
However, storeExportWithContentIdentifier has many more failure modes,
since it needs to avoid overwriting modified files. So it's more
important it have better error display.
The test suite was intermittently failing with rsync complaining it
could not write to dest.

rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1207) [sender=3.1.3]
It seems that the first rsync actually transferred the file, but then for some
reason git-annex thinks it failed, so it retries. The second rsync then fails
because the first rsync copied the file mode over and so the file is not
writable now.
So, this fixes that problem, but leaves open the question of why git-annex
would think rsync failed when it wrote the file and didn't output any
error message. Possibly a bug in rsyncProgress that either hides an
error message, or somehow makes rsync unhappy?
* merge: When run with a branch parameter, merges from that branch.
This is especially useful when using an adjusted branch, because
it applies the same adjustment to the branch before merging it.
On second thought, the extra time running the test suite is worth it.
It will be gained back once we finally get rid of direct mode.
There are two failing tests, same two that have been failing on windows
(though the failure does not look identical). So this should also spare me
the Windows VM while fixing.
The sync is only to sync up the adjusted branch, not other info.
Since many tests use their own special remote named "foo",
the push broke later tests.
This way a failure to clean up the main repo dir from a previous pass
can't result in reusing that repo, which won't be configured right for the
current pass.
