selftests: net: fib_tests: remove duplicate log test

BugLink: https://bugs.launchpad.net/bugs/1915195
[ Upstream commit fd23d2dc180fccfad4b27a8e52ba1bc415d18509 ]

The previous test added an address with a specified metric and check if
correspond route was created. I somehow added two logs for the same
test. Remove the duplicated one.
