Flip order of assert.lte arguments in logical_time_metadata.js

This check in logical_time_metadata.js is meant to succeed if the cluster time in a command response is >= the last applied opTime returned from replSetGetStatus. The timestamps are compared using timestampCompare, which returns -1 if the first argument is smaller and 0 if the two arguments are equal. Currently the test uses assert.lte(0, <timestampCompare result>), which throws if 0 is not less than or equal to the result, so the test will incorrectly fail if the result is -1. The order of the arguments passed to assert.lte should be flipped.
