[profile] Test error reporting by writing to a temp directory

This test case is meant to check whether verbose error logging works. It
does this by _failing_ to write a profile to a path corresponding to a
directory. Make this clearer by writing to a temporary directory.

Patch suggested by Sean Silva!
