Attempt at normalistion of comparison styles - empty string on left and right hand side normalised to it being on the rhs
Before this change, there were (? being regex 0 or 1)
"" ===? 1
'' ===? 24
"" !==? 8
'' !==? 32
== "" 14
== '' 344
!= "" 9
!== "" 4
!= '' 151
!== '' 85
Rhs was the much more common, and the preferred style by many developers.. (Was a similar discussion in #mediawiki recently.. After that lolbugreport i think)
Where there is a string (non empty) on the lhs, and variable/method call on the rhs still need normalising
