Bug 309943 - When unable to obtain a lock, no option to open another file

Currently when you get the message that GnuCash could not obtain a lock
for the file to be opened you have four options...

Open Read-Only, Create New File, Open Anyway, Quit

This commit changes the 'Create new File' to 'Open with No File' which
allows the user to then select...
'File->New' to create a new file,
'File->Open' to open a different file or one chosen from the history or
'File->Quit' to exit.
