Guard against null relevancy condition in SyGuS (#4033)
Fixes #4025.
Also makes our sygus default grammar for strings (slightly) better by including a dummy character, which is required for solving the regression added by this PR. A more robust (but unintuitive to the user) solution would be to include str.from_code( Start_Int ).
