Rework internals of ApiRequestPager (#518)

Browse source 
## Description
Changes how `init()` works for `ApiRequestPager` so that it 1) always
forces updating the total count if needed and 2) propagates errors
during the initial fetch up to the original caller

This means if an error occurs during the initialization of the pager
data, it won't be quietly logged and ignored. Instead, ViewModel code
will catch it and display an error in the UI.
