Fix redirecting stdout for tblastx and tblastn

Workum, Dirk-Jan van requested to merge fix_blast_output_file into develop

We discovered that something goes wrong when running tblastn with pantools. Specifically, this error message will be thrown:

Looking into the code, it appears that specifically for tblastn and tblastx it says >1 instead of 1> for redirecting the output. This causes the actual output file to never be written to.
