rejectattr with equalto filter is not working

[garfieldgroup]

I believe this issue is the same as issue #78, except that rejectattr is concerned.

topics|rejectattr("name", "equalto", "News")

TemplateSyntaxException: com.hubspot.jinjava.interpret.InterpretException: equalto test requires 1 argument

I've faced the same issue with the rejectattr filter.

A typical use case for the rejectattr filter is when one wants to "reject" the current blog post from a list of blog posts fetched that are to be shown in a "related blog posts" section.

One would do, some_blog_posts|rejectattr("absolute_url", "equalto", content.absolute_url)

But the above produces,
TemplateSyntaxException: com.hubspot.jinjava.interpret.InterpretException: equalto test requires 1 argument

Of course, we can work around this using an if/unless statement as described in,

I used to face a similar issue with the selectattr filter; however, it seems to be fixed following #80

Anyone interested in taking a stab at this one? It should be a similar fix as #80 .
