Improve documentation of bp_has_profile()

[antonioeatgoat]

The documentation of bp_has_profile() misses to cite many arguments accepted. I know there is the statement:

@see BP_XProfile_Group::get() for full description of $args array.

But I assume it talks indeed about the description. All the arguments accepted and their default values should be listed, as already done for some of them.
