Pagination doesn't update when created with *ngIf

[StdVectorBool]

We're using ngIf to hide the Pagination component if there's only one page of results and found the component isn't subscribed to DefaultTableStatePagination's events.

This line uses table.tableStateChange events to register listener for tableState.pagination.changed:
https://github.com/hoveytech/ng2-power-table/blob/565ffa9caa1d0e349cca1d2075a665fc2cc8b8d8/src/Pagination/Pagination.component.ts#L51

but those events are only fired on init or reference change:
https://github.com/hoveytech/ng2-power-table/blob/0c870a451b97530147bbad31acf898089c83bdc3/src/Table/Table.directive.ts#L62
https://github.com/hoveytech/ng2-power-table/blob/0c870a451b97530147bbad31acf898089c83bdc3/src/Table/Table.directive.ts#L70
https://github.com/hoveytech/ng2-power-table/blob/0c870a451b97530147bbad31acf898089c83bdc3/src/Table/Table.directive.ts#L85

So if Pagination is instantiated (or deleted and re-instantiated) after Table is already up and running then it never registers for the tableState.pagination events.

Binding to the component's 'hidden' attribute is a work-around but has other issues that make ngIf the preferred method for conditionally displaying a part of the DOM:
