Support for drush 9.0.0-rc1 (changed alias file naming convention again)

See

Simplified site aliases. Fixes #3107 (#3184)

More specifically: drush-ops/drush#3107 (comment)

I updated drush and was driving me nuts why aliases were not there.

Renaming group.alias.yml to group.site.yml

Kind of worked.

There's another issue though, which is that running platform drush-aliases -r now doesn't work because it runs:

drush @none sa @OLDGROUP

If you are creating aliases for the first time and group is not there, before it simply return a string but the command was OK, now it throws an exception so the aliases can't be generated.

The above becomes the norm when you update drush as it simply find no aliases.

I'm not sure I understand the last part - what exception is thrown? It's supposed to be OK with no aliases being found:

Ah... reproduced. The error message changed from Not found to Site alias not found...
