(testsuite) Removed local short timeout values

The local timeout settings `-timeout 1' in some loops seemed to cause
inpredictable results, e.g. with `./runCompletion dkpg.exp' since this
test has a long list to match.  Sometimes the `spawn_id' was gone before
the `teardown' method was called.
Removing the short timeout seems to give more predictable results.
