test-sqlitestore: run sqlite3 with no init file

These tests were failing for me because I have a ~/.sqliterc that
alters the default output. Tests should ignore any init file.

 Can make a local commit
 
   $ hg init local-commit
   $ cd local-commit
   $ echo 0 > foo
   $ hg commit -A -m initial
   adding foo
 
 That results in a row being inserted into various tables

   > SELECT * FROM filepath;
   > EOF
