MT#58530 Fix regex to ignore tables

The exception '.+/accounting/cdr_[0-9]{6}/.+' ignores all elements of a
table (columns, indexes, etc) but not the table itself. It cases error:
=======================
Element: tables/accounting/cdr_202205 is missing in json file
=======================

So fix the regex.
