Embedded Node settings: wait for graph sync

[kaloudis]

Description

This PR adds a setting for Embedded Nodes, waitForGraphSync that prevents users from attempting to pay lightning invoices before the node is synced up graph. It is on by default. Alpha testers have noted that sending before this sync often puts payments in flight without confirmation of settlement. Users might end up sending multiple payments or getting confused.

Users will also be prevented from attempting to pay lightning invoices before the node is synced to the graph and before they have at least one active channel. Users will not be able to opt out of this check.

Lastly, the PaymentRequest view now has an indicator showing that LND is getting ready to make payments. The pay button will be disabled until LND is synced.
