@assert_on_string false positive

[Stadly]

If an assert starts with a string, such as assert('foo' === $bar), PhpDeprecationDetector outputs an error:

Function usage assert() (@assert_on_string) is changed.
You should avoid using string code: 'foo' in assert() usage

By changing to assert($bar === 'foo') no errors are output.
