fix(test): Replace tag and hash for find transactions related apis

When ENABLE_STAT is enabled, every api will be tested for TEST_COUNT times.
send_transfer will issue TEST_COUNT transactions with tag defined in
test_define.h which find transaction related apis also use to get
transaction info.

But after a few more times of execution, the size of retrieved transactions
will get larger than the valid storage of redis cache server, then driver
test would crash.

This fix defines FIND_TAG_MSG and TRYTES_81_3 for retriving and another
TAG_MSG for send_transfer that we can confirm the retrieved transaction info
would not get larger.
