eth-deposit service does not reconnect to Parity node on failure

[bakhtin]

eth-deposit service does not attempt to reconnect to Parity node if just a single request failed. It throws an exception and just 'hangs':

The service should be able to handle situations like this and try to reconnect.
Also, take a look at the log format in the exception. It differs from other logs:

Exception log format (bad):
May 22, 2019 10:30:02 PM okhttp3.internal.platform.Platform log
Other logs format (good):
[22.05.2019 22:29:34,611] eth [INFO ] [eth-deposit:web3j:th-1:id-19] Ethereum chain handler for block 7807067

UPD1: Hit us once again. Here is the link to the logs
