fix: fixes for path mappings, tests, and coverage (#1359)

* fix(): Multiple fixes for path mappings:

* Removed invalid test case that was throwing path mappings  tests because of a typescript bug.
* Readded PathsPlugin for Path Mappings
* Removed coverage preprocessor which was throwing bad type errors against ts code when it shouldn't be.
* Added sourcemap support for istanbul instrumenter. Coverage files are still being generated.

* fix: fix the way the build command runs for mobile tests

* fix: fix the way the build command runs for mobile tests

* fix: replaced promise based ng command with sh.exec to allow mappings test to run correctly against mobile

* fix: replaced promise based ng command with sh.exec to allow mappings test to run correctly against mobile
