0ff75e7a88 Fixed memory leaks in non-gui tests 
Fixed 2 memory leaks in production code and a few in testcases. As a
result leak_check_at_exit ASAN option does not need to turned off for
non-gui tests.
Smart pointers should be used elsewhere for consistency, but the sooner
this fixes are delivered, the lesser memory leaks are introduced.

This additionally makes keySize() and blockSize() work before
setting the key and IV. Required for SSH agent decryption.
