Fix empty directories being created

Adding entries to the root of $PASSWORD_STORE_DIR caused empty
directories of the same name to be created, e.g.

         $ spm add test

would add both the desired entry $PASSWORD_STORE_DIR/test.gpg as well as
an empty directory $PASSWORD_STORE_DIR/test/.

Thanks to Svyatoslav Mishyn <juef@openmailbox.org> for reporting this.
