Unflakify deployment tests (#449)

Browse source 
This PR builds on top of #447 and #448. Since these might be rejected, there will be some changes needed for this PR as well. Let's see how the discussions go in #447.

In the meantime, @fricklerhandwerk, would you mind (in)validating the core idea of this PR? You only need to look at 7cf43c4041, really.
