File lexing fails on junk characters inside strings, breaking Calva in that file

[PEZ]

When there is some unrecognised character inside a string, the lexer croaks and then the token cursor can't be created which means that about all Calva functionality dies in that file.

Reproduction

Here what looks like a space inside the string, is really something else.

(def foo
  [" ("])

Since I don't know if the funny character gets pasted correctly, here's a zip: tiny.cljc.zip

Expected: Things should tick on as normal, Rainbow parens, evaluations, paredit, formatting.

Actual: All that breaks.
