Remove new from reserved keywords
This effectively allows stubs to be placed on the `new` method for types.
A strange issue arose when the keyword was allowed.
The compiler failed to resolve the Stub type from the Double initializer.
The error trace goes through null_double_spec.cr.
Running just that spec file confirms the issue is there, but running other individual files doesn't produce the error.
As a workaround, I've put the full path of Stub in the initializer.

Remove type resolution

This is why types could not be found within the spec.

I haven't been able to reproduce this in a simplified form.

Passing the `constraint` argument in NullStub#and_return to ValueStub.new triggers the bug.
Removing the `constraint` argument fixes the issue.

Fix call expansion in debug log
Macro expansion somehow generated an error when calling a missing method with a block.

```
syntax error in :1

Avoid issue with TypeCastError message
For some reason, attempting to get the class of the stubbed value causes a segfault.
This appears to get swallowed in some cases.
Trying to inspect the value was difficult without triggering some error.
In the failing case, the value is 42 (returned by a stubbed foo method).
The method is supposed to return a String, and this error checking should be triggered (line 119).
The value is a union, and inspecting the bytes contained in it looks like it's prefixed with the Crystal type ID for Int32.
However it looks like Crystal tries to treat it as a Bool? I'm not sure.
Very weird behavior and instead of wasting more time on it, I'm omitting the returned type from the error.
This type of casting error shouldn't be common.
This seems like a Crystal bug, but I'm having a hard time distilling the issue.
