Fix popup error due to uninitialized members

Add code to initialize member variables in Popup's constructor and
to check whether the value from elm_entry_entry_get() is null or not

When cert popups are opened in succession, elm_entry_entry_get() returns
null occationally. So it needs null check.

Until now, Popup's boolean member variables have not initialized. So
Popup::Result() enters code about entry although Popup doesn't use entry.
It needs to initialize member variables with proper values.
