Sven Klemm 11c6813b1d Fix flaky regresscheck-shared 
While we do filter out chunk ids and hypertable ids from the test
output, the output was still unstable when those ids switch between
single and double digit as that changes the length of the query
decorator in EXPLAIN output. This patch removes this decorator
entirely from all shared test output.
