The prefer-to-have-count rule does not deference expect arguments to verify their assigned value.

[An631]

The current prefer-to-have-count rule has a problem where any expect checks that take a variable argument will not check to make sure the value is not originating from a .count call.

For example the following code would not be flagged as an error:

   const filesCount = await files.count();
   expect(filesCount).toBe(2);

The current code misses this case because we are not dereferencing the last assigned value of filesCount at the moment of verifying the expect argument. The rule should flag the error and return the following as a fix:

   const filesCount = files;
   await expect(filesCount).toHaveCount(2);
