Include current task runtime in ulTaskGetRunTimeCounter (#1234)

Browse Source 
* Include current task runtime in ulTaskGetRunTimeCounter

Update ulTaskGetRunTimeCounter to include elapsed time since the last
context switch when called for the currently running task. Previously,
this time was not included in the calculation.

Fixes #1202.
