Subject: [PATCH] Import: don't assume an empty file is a text file

Since in any case, the empty file has nothing to import and it's admitted by
SQLite as a valid database, it's better to revert to the previous behaviour,
where an empty file dropped or opened by the file manager was treated as a DB
and indeed worked.

The behaviour was changed by cfa4dee3be69ace34cfdd4c2b4a8accc067bdbe7

See issue #2636
