Pull request: jinja: fix macro with kwargs

## Overview

Fix this case: `{% macro my_func(a, b=False) %}{% if b %}{{ a }}{% else %}nope{% endif %}{% endmacro %}{{ my_func(1, b=True) }}`

With the `master` branch version, it fails with this error:

```
UNHANDLED EXCEPTION (test): 
------------
While executing If at line 1, column 35 in source:
...{% macro my_func(a, b=False) %}{% if b %}{{ a }}{% else %}nope{% endif %}{...
                                     ^
Error: KwArg is not a bool value
```
