Tilt tests started to fail after the latest changes. Had to make
some fixes and optimizations so that the test code resets the
tilt controls correctly and aligns with relay_chn's timing requirements.
Fixes #1115
TAG constant is only used when run limit is enabled. As a result,
the compiler generates an "unused variable" warning for other cases.
Fixed this warning by adding the unused attribute.
Fixed test_apps directory locating issue by fixing the path to
"project_root/test_apps" and removed find command since it
searches recursively and founds the similar directories in
managed_components directory. Also added current time to the output.
