Title: Test packages

- Adding tests for package deps
- Adding conflict/override warnings for package deps
- Adding cycle detection for packages
- Adding cycle detection for mixed packages+source
- Fixing internal dependency format of package resources when converted
to rebar_app_info
- normalizing level-order prioritization to be based on lexicographical
sort of app names rather than traversal order (which is undefined for
package deps)
- Fixing tests for source deps for deep cycle detection
- Fixing bugs with source deps
- Relaxed version format checks for test utils
- fixing an error message to mention `rebar3` instead of `rebar`

A lot of fixes are combined in there because I didn't want to commit
non-passing code, and many bugs were found when adding the second batch
of tests as part of the original effort.
