litecli 1.12.2_0+python38 conflicts with py38-dogpile-cache @1.0.1_0

Attempting to upgrade litecli resulted in the following activation failure for me:

This conflict should either be marked, or fixed. (I haven't tested litecli's other python variants to see if they also have conflicts, but they very well might, too)

Neither of the packages should install a tests directory in the site-packages; it should either not install these at all or they have to be tucked away in ..../site-packages/<portname>. There are several other examples of Python ports in the portstree where that has been done, so you can take a look and submit a PR if you're interested in fixing this.
