rerunning BLAST from same instance of tool puts unformatted data at bottom without removing previous results

[Elaine Meng]

I don't know if this is widget flakiness and/or lack of clearing previous results, but if after Blast results are returned, I change parameter settings and click Blast again from the same instance of the tool, the previous results stay there but I get a whole additional unformatted data dump below it. The data dump part is much wider because it shows all of the columns no matter what things are checked in the columns menu. Screenshot showing junction between previous results and datadump attached.

Fixed in 3e4701234.

The bootgrid table was used incorrectly. Instead of deleting and recreating the table each time data is updated, just clear the table and add data as new rows.
