Fixed compilation of filter_iterator conversion constructor.

Browse Source 
The constructor would attempt to access a private member of the source
iterator, which could have a different type and therefore have that
member inaccessible. Also, the storage forwarding constructor had incorrect
types used in the forwarding expressions, which caused further compilation
errors.

Fixes https://github.com/boostorg/iterator/issues/90.
