Philip Withnall 5f6b1516ae tests: Rework how slow param test is skipped 
It’s more helpful to always register the test, even if it’s normally
skipped, since then the skip is recorded in the test logs so people can
see what’s ‘missing’ from them.

* *-rwc rw, rwc Must not add any restrictions
* *-rwC rw, rwc, rwC Can remove 'construct-only' restriction

* *-wC rwC, rw, w, wC Can add readability or remove 'construct only' restriction
* rwc, wc
*

*
* - 0: invalid because the interface property doesn't exist (invalid flags)
* - 'v': valid
* - 'i': invalid because the implementation flags are invalid
* - 'f': invalid because of the removal of functionality
* - 'r': invalid because of the addition of restrictions (ie: construct-only)
*
* We also ensure that removal of functionality is reported before
* addition of restrictions, since this is a more basic problem.
