Filter bp_has_groups query args

[Offereins]

Currently there is no convenient way to prevent bp_has_groups() from using $_GET['s'] for querying groups matching search terms. Bypassing this behavior would be great for use cases where the groups query is not the primary page query and thus should ignore the search parameters, possibly among others.

Suggested is to add a filter before sending the query args to BP_Groups_Template().

Adding a filter to the arguments is a pretty general solution to this specific issue. The problem is that bp_has_groups() is a bully about the 'search_terms' argument: it overrides values passed to the function, in favor of those found in the URL parameters. Let's correct this issue before adding general filters.

So, in brief, you can ensure that search params won't apply like this:

if ( bp_has_groups( array( 'search_terms' => false, ) ) ) : // ...

In 8116:

Auto-fetch URL search parameters in bp_has_groups() before parsing $args array

Our previous method, of getting the search term out of $_REQUEST, had the
effect of overriding any search terms that were passed to the bp_has_groups()
function. Among other problems, this made it impossible to get an unfiltered
group list when looking at a page that was using an 's' parameter for something
else.

Fixes #5456

In 8447:

Set default search terms before function params are parsed in bp_has_blogs()

By getting the default value of the search_terms parameter from $_REQUEST
before parameters are parsed, we ensure that 'search_terms' is passed to the
bp_parse_args() filter in the same way as the rest of the function params.
