[Bug]: No constraints or retry attempt when failing to obtain price data for conversion resulting in error when interacting with Blocktank

[catch-21]

Describe the bug

If Bitkit starts without being able to retrieve price data (has happened to me a few timesunder normal conditions) and it doesn't have past data to use then it displays a dash for the dollar value (see first screenshot). From then on it does not attempt to fix this state even if network conditions are good. As a result, there is no price data for creating a LN channel (see second screenshot).

It would be good to prevent access to any action that requires live price data on the client side.
It would be good to retry obtaining price data if it has been unsuccessful.

Reproduce

1. With no network (aeroplane mode)
2. With a new instance of Bitkit
3. Create a new wallet
4. Allow network access (disable aeroplane mode)
5. Tap the 0 bitcoin balance to display dollar
6. Observe a dash for dollar price instead of 0 (this is probably an ok representation but there are no attempts to update live price data, even with a manual pull-down to refresh)
7. Tap Receive at the bottom
8. Tap Receive on Spending Balance
9. Input valid amount and Continue
10. Observe 'Undefined' fiat amount in description
11. Tap Continue
12. Observe CJIT Error and no progression to create invoice

Screenshots / Recording

Dollar value displays with a dash when there is no price conversion info

Attempting to create CJIT channel displays 'undefined' and produces error

Log output

No response

[catch-21]

Tested on v118
This is much improved. I see that the price data is updated automatically and correctly.
However, I did notice that the $0 service provider fee and CJIT Error: init_channel_manager can be provoked when attempting to receive spending balance with no network.
@limpbrains would you suggest addressing here or in new issue?
