Subject: [PATCH] no partial match if trailing data is invalid utf (#238)

Avoid returning a partial match if one was found but followed by invalid
UTF, making the result consistent with JIT and unlike:

PCRE2 version 10.34 2019-11-21
    re> /.a/match_invalid_utf,allvector,jit
  data> b\xb1\=ph,ovector=1
  No match
   0: <unchanged>
  data> b\xb1\=ph,ovector=1,no_jit
  Partial match: b\x{b1}
  ** ovector[1] is not equal to the subject length: 1 != 2
   0: 0 1

Conflict:NA
