tester-cli: flags not forwarded when running command programmatically

[Nigui]

Describe the bug
In the Vote command of tester-cli, Transfer command is called to initialize wallet balance (source)

Overriding base command flags (like p2pPort) during the vote command call, make transfer command crash due to invalid port used (default port of base command instead of source command port value).

It produces the following error:

[1550055840041] ERROR (core-tester-cli/28311 on laptop.local): Failed to get network config:  connect ECONNREFUSED 127.0.0.1:4002
error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

To Reproduce
Steps to reproduce the behavior:

1. Start a testnet node (p2pPort is 4000 by default)
2. Go to core-tester-cli
3. yarn tester vote [...] --p2pPort 4000
4. See error

Expected behavior
flags used in source command should be forwarded to programmatically called commands.

Tried to give this.options as second parameter of Transfer.run(...), but it produces the following error:

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined

Maybe solution should be to manually forward flags, serializing as a string array and passing to Transfer.run first parameter.

Will take a look next week when I find time unless you've send a PR by then @Nigui.
