Fix signing keys and txs folder on remote

[samuelWilliams99]

When operating with a remote CLI, I noticed a few issues:

• Balancing transactions required the signing keys file to be on the remote machine, but they weren't written until submission
• The txs folder is always created on the local machine, whereas, if we're running remote, it needs to be on the remote machine
• Various files and directories are created in non-optimum places

LGTM.
I assume you have already checked with a real remote server.
Might not really worth the effort, but I think we could extend the MockContract testing framework so that it checks for files on cli calls, so we don't run into the same kind of trouble after a refactoring.

Yep I've tested on real remote. I havent however tested on local, as I dont have that environment readily available. I don't expect these changes to even remotely affect Local, but it might be worth checking if you know of a quick way to do so?

[szg251]

I'll just check them myself

[samuelWilliams99]

As for testing, how do you mean? Would we keep track of a mock file system and parse the cli calls to ensure they refer to existing files?

[szg251]

We already have that mock file system here: https://github.com/mlabs-haskell/bot-plutus-interface/blob/master/test/Spec/MockContract.hs#L198 but it doesn't handle uploadDir yet
cli call parsing could get a bit tedious

@samuelWilliams99 Did a few tests with the examples on the local environment, it looks good.

Depends, we dont need to parse the whole thing. theres a set of specific flags that are followed by a path, we can just look for those then grab the next thing up to a space (or quoted)

[samuelWilliams99]

I think the tests would probably go best with the tx delete changes, as we can generalise to ensure that works as well

[samuelWilliams99]

Or, at the very least, a new ticket. This one is a bug fix

Going to handle the mock file system improvements in #65
