Increased stack to 1024 from 768 and corrected assert.

1) mbed-os-tests-mbedmicro-rtos-mbed-basic tests use to fail when run in loop
after 20-25, This was because the stack used by test application was in range of
744-840 bytes. So bumped the stack size to 1024 bytes.

2) Corrected the assert and taken out the assert which was not required.
