When we deactivate a tempfile, we also have to clean up the
"filename" strbuf. Let's pull this out into its own function
to keep the logic in one place (which will become more
important when a future patch makes it more complicated).
Note that we can use the same function when deactivating an
object that _isn't_ actually active yet (like when we hit an
error creating a tempfile). These callsites don't currently
reset the "active" flag to 0, but it's OK to do so (it's
just a noop for these cases).
