Essentially, other tests may set breakpoints and the Id is ever
increasing, so a test for Id 0 will only be true if this is the
first time a breakpoint has been set in this session
This restructuring moves tests to a directory name which matches the module
in which the cmdlet resides which should improve the discoverability of a
specific test.
For tests which are not about cmdlets in a module, new directories have been
created to make those tests easier to find as well
