Before that change the code would do the following:
1- if dependency is installed, continue
2- if dependency is queued, continue
3- get dependency from repos
After that change the code does this:
1- if dependency is queued, continue
2- if dependency is installed, continue
3- get dependency from repos
So the dependency is checked if it has been queued as the first phase, which
seems to be the most common path in most cases.
