Fix messed up table browser

Browse Source 
This is to work around a Qt bug which is present in at least version
5.7.1. The problem is this: when you browse a table/view with n
colums, then switch to a table/view with less than n columns, you'll be
able to resize the first (hidden!) column by resizing the section to the
left of the first visible column. By doing so the table view gets messed
up. But even when not resizing the first hidden column, tab-ing through
the fields will stop at the not-so-much-hidden rowid column, too. All
this an be fixed by this line. I haven't managed to find another
workaround or way to fix this yet.

If anybody knows more about this issue please let me know.
