Sync parserTests with core.

This matches upstream commit bd1ac41578a352cd370ad6c02a2352d8372def37.

It contains updates to the normalizer and blacklist to account for:
 * TOC changes (I4ecd0659d1f955a9b593d281a3fef0a81c218a52)
 * Brackets in edit links (Id27555c6dee250eafeefa97ae8927438fd65b8d7)
 * Relative inclusions in Main (Ie04f23c180e501631c629a39b997796a1725fb67)

It's likely that the blacklist items added for the new tests added by
"Relative inclusions in Main" are actually valid bugs (ie, parsoid's
behavior no longer matches upstream).  I will address these in a
follow-on patch.
