imp: remove default application of profileTests

now that we have per-host custom tests, it does not make sense anymore
to have magic lumpsum tests.

users are encouraged to use the new digga.lib.allProfilesTest standard
test and add it to a host's test like so:

`nixos.<host>.tests = [ digga.lib.allPrefilesTest ];`

 ## Integration Tests
-All your profiles defined in suites will be tested in a NixOS VM.
+All your profiles defined in suites can be tested against an individual host.
+Simply use digga's pre-baked `digga.lib.allProfilesTest` like so:
+
+```nix
+{

 You can write integration tests for one or more NixOS VMs that can,
 optionally, be networked together, and yes, it's as awesome as it sounds!
 
-Be sure to use the `mkTest` function from Digga, `digga.lib.pkgs-lib.mkTest`
+Be sure to use the `mkTest` function from Digga, `digga.lib.mkTest`
 which wraps the official [testing-python][testing-python] function to ensure
 that the system is setup exactly as it is for a bare DevOS system. There are
 already great resources for learning how to use these tests effectively,
