Add ability to delete a payment from home screen

[niteshbalusu11]

Add ability to delete payments from home screen which are entries in the SQLite db of Blixt, like if you don't want a specific payment to show up on the screen. They could always be refetched from LND if necessary.

The alternative for this could be to have a hidden field that hides payments you don't want to show up and hidden payments could be viewed elsewhere or can be unhidden when necessary.
