username, uid, and email settings description incorrect

[tbfisher]

in stanford_ssp_configuration_form() each of these settings state in the field description

"If the attribute is multivalued, the first value will be used."

however the getter functions

• stanford_simplesamlphp_auth_get_authname()
• stanford_simplesamlphp_auth_get_username()
• stanford_simplesamlphp_auth_get_email()

assume it is an array and always fetch the first value

Oh I see, each of those functions is assuming array and should validate the value in the attributes array for single vs multiple values.

An is_scalar check is needed here I suppose.
