Docket report error strings with unescaped periods causing parser validation to fail

[nadahlberg]

Another small one:

"Case not found." is causing this docket fail (txsd 2:20-cr-00606):

I think the problem is that some of these error strings have literal periods whereas other strings include patterns (e.g. "The case type was.*but it must be").

Since we have both would it just make sense to escape all the punctuation manually?
