Number of block confirmations do not update if BTCEXP_NO_INMEMORY_RPC_CACHE is set to False

I've noticed this behavior when running BTC-RPC-Explorer in regtest, I can't speak to whether it happens on main or testnet. The workaround is pretty simple, but figured I'd bring it up in case it's unintended behavior.

Once I visit a block page, the number of block confirmations it has will not update. For instance, if I look at block 113 for the first time since the server has been started and the latest block is 114, it will correctly show 2 confirmations. However, if I generate another X blocks and either refresh the block 113 page or close and revisit the block, it will still only show 2 confirmations. If I then open the block chain explorer on a completely different computer and visit block 113, it will still only show 2 confirmations. The accurate number of confirmations a block has is reflected if the server is restarted with BTCEXP_NO_INMEMORY_RPC_CACHE set to "true" in the .env file.

Environment (please complete the following information):
btc-rpc-explorer: 1.1.9
Bitcoin Core 0.19.0.1

This is an issue of caching. Your workaround (disabling caching) is definitely a good fix if you don't need caching.

I'll need to think about how best to address this issue...
