#377 tau_tti: tau_getOwnIds doesn't check the cache correct

[Anders Öberg]

In tau_tti.c funciton tau_getOwnIds

It is not correct to check:
if (appHandle->pTTDB->noOfCachedCst == 0)
Can be any cst in the cach it may not be own cst that we need. Depends on previous made requests.

Suggested change to
if(appHandle->pTTDB->cstInfo[0] == NULL) / own cst info is always stored on entry 0 /

[Armin-Hagen Weiss]

Suggested change implemented. To be tested.
