Users updating packages can't understand output of pub

[matanlurey]

Tracking issue for dart-lang/pub#912.

Until this is complete, and rolled out, we can't release v5.0.0-final - our users have to go through mental gymnastics in order to figure out how to solve error messages like:

Resolving dependencies...
Package angular_components has no versions that match >=0.9.0-alpha+8 <0.10.0 derived from:
- merck_crm_mashup depends on version ^0.9.0-alpha+8
Process finished with exit code 1

That's quite a common error message from pub - not only with Angular.
It also happened with every Angular release when used with angular_components when pub upgrade is run before the matching angular_components package was released which is usually a several days after an Angular release.

Isn't this fixed with 2.0.0-dev.44.0 and the new pub version resolver release? (mentioned in issue)

Yup, happy to close this.
