Old Salt files can conflict with new `make dev` run

[eloquence]

On a Whonix 14 system, running make all failed with "Recursive requisite found", specifically reporting issues with the IDs anon-whonix, sys-whonix-template-config, whonix-ws-15-dvm, and qvm-appmenus --update whonix-ws-15-dvm. Full logs here:

After poking around at issues with Whonix updates, I re-ran the relevant Salt state with sudo qubesctl state.sls qvm.anon-whonix. This produced the output logged here:

After this command, a make clean && make all run completed without error.

It seems like a salt file in your /srv/salt directory was conflicting with the latest changes introduced in master. Our make all target does not clean salt prior to running https://github.com/freedomofpress/securedrop-workstation/blob/master/Makefile#L10 . Perhaps calling clean-salt prior to prep-salt might resolve here.

We should also consider a sd-specific folder in /srv/salt/ to ensure reliability of salt cleanup.

The suggestion to run clean-salt prior to prep-salt is tracked in #434, so closing this specific report that is likely just a symptom of the issue.
