Fix VEP `--failed` flag  

the `failed` flag should be a flag per the documentation
(see:
 http://grch37.ensembl.org/info/docs/tools/vep/script/vep_options.html,
and
http://oct2014.archive.ensembl.org/info/docs/tools/vep/script/vep_options.html )
But, when running, it requires a numeric value.
When running the VEP with verbose mode, it
appears that all boolean flags get converted to 1.
Therefore, I'm setting `failed` to have value 1.

This bug has been reported to Ensembl. It occurs in all versions, including most recent version 82.

@p.j.van_t_hof Should we include a failback mode, in case Ensembl fixes this in version 83?
