Master/dev builds don't quite work

[ZLLentz]

In my latest PR the master/dev build fails with a conflicted environment.

The dev test works by using pcds-dev as the first channel, so it's probably one of the following things:

• Tags don't exist on pcds-dev, so when the dev channel is used, a minimum tag is required, and at least one packages has no PRs from after the most recent tag, it's possible that there isn't a way to satisfy the dependency.
• Since we've put packages onto conda-forge and the dev test works by using pcds-dev as the first channel, and since the recipe in each repo that gets uploaded to pcds-dev is not necessarily the same as the one on conda-forge, the dev build doesn't behave the same way as the tag build will. (E.g. at least one of our internally used recipes are broken)

Once we move to the usage of the pcds-ci-helpers it will also address this issue since it uploads to both pcds-dev and pcds-tag... conda-forge is the same as pcds-tag...
