[PATCH] testbot/web: Fix picking which module to test.

[Francois Gouget]

Make sure Submit.pl picks the module with the modified tests even if
the patch impacts other modules.

This only impacted the suggested command but could be confusing. Whether 
the command was correct or not depended on the order in the hashtable.
