[BUG] pip.installed show stacktrace when user does not exists on testing

[SndR85]

Description
When I'm creating a state with pip.installed, with an user given and will apply this state with test=True then there will be a stacktrace because it's trying to figure out which packages are installed under that user. However the user does not exists, so it will fail to check.

Setup

Install Salt 3006.3 on local linux machine. Install pip with your preferred package manager.

Steps to Reproduce the behavior
Create this state:

pip.sls:

Flask:
  pip.installed:
    - user: fred

The user fred does not exists. I'm applying the state:

# salt-call --local state.apply pip test=True
[ERROR   ] Pre-caching of PIP packages during states.pip.installed failed by exception from pip.list: User 'fred' is not available

    pwd.getpwnam(runas)

During handling of the above exception, another exception occurred:

Expected behavior

When applying the state and test=True, something like this should be shown:

Additional context
I have installed Salt from the github repository with pip, checked out on tag v3006.3.

[SndR85]

I'm not sure if the changes should be shown. Maybe, the result should even be False, because the user isn't found and it cannot check if the package should be installed.

It would then return something like:

[ERROR   ] User fred does not exist
local:
----------
          ID: Flask
    Function: pip.installed
      Result: False
     Comment: User fred does not exist

     Changes:

Which is I think more the way it should be?

[SndR85]

When I'm lookung further into it, I even think that it should alsof fail with the same error when not running in dry-run mode. Currently, If I'm applying a pip.installed state with an unknown user I get the same stacktrace. This should also be the neat output like:

[ERROR   ] User fred does not exist

      Result: False
