Description of problem:
If you want to resubmit a task to beaker using "make bkradd", you have to run "make tag" at first, otherwise the task does not get updated in beaker.

Version-Release number of selected component (if applicable):
rhts-test-env-4.30-1.fc14.noarch

How reproducible:
always

Steps to Reproduce:
1. cd to the testcase dir
2. open the corresponding task info page in beaker, note "Updated Date"
3. update the testcase somehow
4. make bkradd
5. refresh the task info page
  
Actual results:
the task is not replaced with the new version, the "Update Date" stays the same

Expected results:
new task version replaces the old one in beaker, "Update Date" changes to the time of submitting the new version

Additional info:
it is quite annoying to find the test didn't get updated despite the fact that submitting it (via "make bkradd") did not report any error ...
