fix(discovery): allow requireUpdate util to timeout in discovery/file/file_test.go.

Browse Source 
The loop ran indefinitely if the condition isn't met.

Before, each iteration created a new timer channel which was always outpaced by
the other timer channel with smaller duration.

minor detail: There was a memory leak: resources of the ~10 previous timers were
constantly kept. With the fix, we may keep the resources of one timer around for defaultWait
but this isn't worth the changes to make it right.
