Delete experiment from users no longer at BSC

Hi @dbeltran

I'm trying to delete experiments from a user no longer working in the department (Muhammad Asif/masif/1244) but autosubmit is failing because it can't associate the uid with a real user name:

pbretonn@bscesautosubmit01:~$ autosubmit delete a00t
Do you want to delete a00t ? [y/n]
y
Removing experiment directory...

It's not a major issue because I can delete the experiments by hand from esarchive and the autosubmit database, but if you have time at some point, it could be useful to fix this.

Thanks!
