Subject: [PATCH] Better error reporting on invalid query

It still panics, but previous error was:
```
thread 'main' panicked at 'Box<Any>', src/lib.rs:190:23
note: Run with `RUST_BACKTRACE=1` for a backtrace.
```
Now it looks like:
```
hread 'main' panicked at 'Bad query: query parse error: Parse error at 1:2
Unexpected `}[Punctuator]`
Expected `Name` or `...`
', src/lib.rs:190:23
note: Run with `RUST_BACKTRACE=1` for a backtrace.
```
