strstr() [function.strstr]: Empty delimiter in bp_is_current_component () when $component is empty

[megainfo]

A php warning strstr() [function.strstr]: Empty delimiter
line 864 caused by strstr call when $componentis empty string or null value.

In 7361:

Ensure $component has been passed before checking is_current_component()

Passing an empty value was causing a PHP warning to be thrown when using
strstr() later in the function.

Fixes #5158

The warning appear in the eleseif condition ( when calling strstr() )

here a second patch (named bp-core-template.php.patch).

In 7366:

Always return false when null value is passed to bp_is_current_component()

This is an improvement on r7361, where only one condition of the component
check was checked against empty values of $component.

See #5158
