test/vim.validate(): assert normalized stacktrace

- The previous commit lost information in the tests. Instead, add some
  more "normalization" substitutions in pcall_err(), so that the general
  shape of the stacktrace is included in the asserted text.
- Eliminate contains(), it is redundant with matches()
