Hotfix: Fix erroneous pathauto module version number.

## Ready State: Yes

In https://github.com/imagex/imagex_installkit/pull/77, the pathauto project definition duplicate was removed but the remaining pathauto definition contained an erroneous 1.7 module version number. Pathauto has no 1.7 version, the latest is 1.2. 

Whoops.
