msm handling of git errors could use some love.

• I'm running a Mark 1

• with mycroft-core and mycroft-mark-1 both at version 18.8.0

• When I run msm update on my Mark 1, it reported a git failure for the mycroft-weather skill. While, in this instance, the trouble appears to be with the weather skill itself, it seems msm might handle such stuff a bit more gracefully, perhaps? Should it offer to try (in this case) the git remote prune origin that it suggested I try?

You definitely got a point here. I wonder if this is a mechanism that should be implemented in mycroft-core or in msm
