vcol.wrong_arena failing on buildbot when current date is '2022-03-17'

Analysis: When current date is '2022-03-17', dayname() gives 'Thursday'. The
previous json state is PS_KEYX which means key started with quote.
So now json parser for path is supposed to parse the key.
The keyname starts with 'T'. But the path transition table has JE_SYN when
previous state is PS_KEYX and next letter is 'T'. So it gives error.
Fix: We want to continue parsing the quoted keyname. So JE_SYN is incorrect.
Replaced it with PS_KNMX.
