Small Staking Commands fix

[0xSpuddy]

Summary

Using the following commands gave an error that the --unsafe flag was unexpected:

telliot stake
telliot request-withdraw
telliot withdraw

Added the unsafe flag to the function definitions for each command. Result is that the commands work as expected, however adding --unsafe -pwd PASSWORD does not bypass confirmations for these staking commands.

In my opinion the --unsafe flag is really only needed for the report command, so this is an acceptable solution! Let me know what you think if different 🤙
