tests: fix account accumulation on Linux systems

On non-dockerized Linux systems, the accounts generated during tests are
only cleaned up occassionally. The test suite design implements
consistent account cleanup post test. Accumulation of these accounts
interfere with subsequent test runs, rendering the test suite ineffective.

The main test scripts incorrectly utilize a Jami Windows environment
variable for Linux systems. In adherence with the Jami client design,
this patch utilizes the correct environment variable for Linux systems.
Windows formatted paths were also modified to allow recogntion in Linux
enironments
