Temporary remove old tests and regtests of v0.0.8

Two reasons: duplicate of existing unit test and no longer compatible
due to the renaming of bitcoind -> mastercored.

I'm very much in favor of adopting the missing parts though, but I
believe it's cleaner to remove this until the tests are converted.
Adopt meta DEx reserved balances on RPC layer
Require enabled wallet

Throws a build error, if configured with --disable-wallet or friends:

```bash
~/mastercore$ ./autogen.sh
~/mastercore$ ./configure --disable-wallet
...
checking if wallet should be enabled... no
configure: error: Master Core must be used with enabled wallet. Please do not use --without-wallet or --disable-wallet.
```

Default behavior is not changed.
