Fix the issue with failing pbm commands by starting logging later after the collection is created

the implementation details were changed. no convertToCapped is invoked. just logging starts later after the collection is created. such code was merged and tested

the root cause is the warning message WARNING: Unsupported MongoDB version. PBM works with v4.4, v5.0, v6.0, v7.0 is put into admin.pbmLog collection before the collection is created as capped. PBM inserts this message into the logging collection which makes the collection regular. then tries to create the collection again as capped but it fails (NamespaceExists).

the fix does convertToCapped if the collection is created but it is not capped.
