Helm: Please add support for using "-" for tramp-default-method in helm-find-files

[laurynas-biveinis]

Is your feature request related to a problem? Please describe.
Without Helm, M-x find-files can use "-" pseudo-method as a Tramp access method to make it use tramp-default-method, i.e. //-:hostname:path would be identical to //scpx:hostname:path if tramp-default-method is set to "scpx". With helm-find-files, I am required to spell out "scpx", it would be nice if "-" were supported too.

Describe the solution you'd like
Make helm-find-files recognize "-" as a Tramp access method and expand it to tramp-default-method, like find-files does.

Describe alternatives you've considered
The obvious workaround is to type "scpx" or other access method instead of "-" myself, ignoring tramp-default-method.

Additional context
In Tramp URLs, "-" is supported under Tramp default syntax (i.e. not the simplified one).

I have pushed a branch implementing this, but I have no ssh server to
test against from where I am actually, so it is fully untested, let me
know if it works for you.

Thanks.

Thank you - I should be able to test this tomorrow and will update

@thierryvolpiatto , I have tested the patch by applying it on the top of 3.6.0 release (not the HEAD - I hope that's good enough) and confirm that "-" now works and expands to tramp-default-method. I did not see any regressions in using "scpx" neither. Thank you!
