only display app version and help message once
...
When processing the flags for -h/--help and -v/--version, only check
the flags in checkVersion() and checkHelp() instead of also printing
the associated message.
This fixes the problem of `app -h` and `app -v` printing their output
twice. The doubling was caused by printing the message once for each
registred alias for the given flags (-h/--help and -v/--version).

Version and help check should look for local flags too
...
Now that Global looks up the chain of contexts, the top level should
access the flags without the prefix (i.e. Bool rather than GlobalBool).

But update signature to take a writer. This is a backwards incompatible
change for those overriding the HelpPrinter, but the hope is that this
feature is largely unused and the usage is easily updated.

- the command name is "" and HasName was returning true for an empty
