test(zhtlc): Use alternative grpc service name for pirate lightwalletd

[smk762]

ref: https://github.com/PirateNetwork/lightwalletd/blob/master/walletrpc/service.proto#L7

Infrastructure for ARRR lightwallet servers uses a fork of lightwalletd which has renamed the grpc service name from cash.z.wallet.sdk.rpc; to pirate.wallet.sdk.rpc;

To use these, the changes in this PR are needed. Once merged, existing lightwalletd servers from ZOMBIE will need to run on the pirate fork of lightwalletd.

Until these changes are merged, a single lightwalletd server configured with cash.z.wallet.sdk.rpc; is available. This server will remain online over the period between next api release and related app releases.

To test:

1. Activate ARRR with one (or all) of the following servers:

"light_wallet_d_servers": [
    "https://lightd1.pirate.black:443",
    "https://piratelightd1.cryptoforge.cc:443",
    "https://piratelightd2.cryptoforge.cc:443",
    "https://piratelightd3.cryptoforge.cc:443",
    "https://piratelightd4.cryptoforge.cc:443"
]

and the electrum servers in https://github.com/KomodoPlatform/coins/pull/811/files

• Confirm activation is successful, and you are able to swap and send/receive ARRR

2. Activate ARRR with the following server:

"light_wallet_d_servers": ["https://pirate.spyglass.quest:9447"]

and the electrum servers in https://github.com/KomodoPlatform/coins/pull/811/files

• Confirm activation fails with "error":"All the current light clients are unavailable."

3. Repeat the second test using https://github.com/KomodoPlatform/komodo-defi-framework/releases/tag/v1.0.7-beta

• Confirm activation is successful

Approved.
ARRR coin activation was completed as expected.

👍

Note for the future: if we would like to support original Zcash/lightwalletd, we will need to add their proto definitions and use them, depending on the ticker of the coin (or make it configurable somehow).
