Partial fix of a bug concerning scrollbar

A widget with a scrollbar tends to request much more room than needed, even if its size is fixed. This fix corrects that, however something is still missing as the widget borders does not draw exactly properly.
BUG: Qt: TableEditor: User column resizing not preserved.

For columns with resize mode == "interactive" with no explicit
width set, the user's resizing of the column should be preserved
when a value changes.
Qt: TableEditor: Scroll horizontally by pixels instead of columns.

Scrolling horizontally by columns is very awkward/jumpy and
difficult to work with. Smooth scrolling is good behavior.
BUG: Keep UI instances alive when `configure_traits()` is called while an event loop is running.
Revert "BUG: Do not rely on an exception message. Look at the CTrait itself to determine if the exception came from an Event trait or not."

This reverts commit 6954ff0130e6d3fb800f4c20454f96328ecceb37.
ENH: Make a note of why parsing the exception message is necessary.
ENH: Test the fixed bug.
