Re #8184. Fix error in generating log message.
Re #8184. Add a test for loading a TableWorkspace.

Fails right now because of the extra whitespace at the end of entries
in the string column.
Re #8184. Remove whitespace at the end of loaded strings.

The entries in columns of string type are, for better or worse,
saved in fixed-length strings which are padded with whitespace.
This removes that whitespace on loading so that the table is unchanged
compared to the original.
Re #8184. Remove code that can't be reached.

Just clearing coverity warnings while I'm touching the file.
Re #8184. Clear coverity warning while I'm touching the file.

The warning was that a dynamic_cast was used, but the outcome not being
checked. This is because we know it to be a TextAxis at this point -
therefore, just use a static_cast.
