🐛 Fixes shell arguments being passed twice to aws command

[hcourse-nydig]

Removes first param from arg lists before calling aws cli. Fixes both bash and fish

Resolves: #375
Resolves: #376

Actually I believe this is wrong. This works, but only coincidentally. I believe it will not resolve #374

The issue is that the new install script (https://github.com/oktadev/okta-aws-cli-assume-role/blob/master/bin/install.sh) lost lines 135-142 from here

okta-aws-cli-assume-role/bin/install.sh

Lines 135 to 142 in ed29abf

	command="\$1"
	profile=\$2
	shift;
	shift;
	if [ "$1" == "logout" ]
	then
	command="logout"
	fi

It's possible that the java bits changed to receive different arguments, but something needs to write the proper profile name into the .aws/credentials file.

Looks like this is the commit that broke things.

@DavidTanner was this change intentional? It seems to have broken things.

@hcourse-nydig I combined what you did with what @DavidTanner did in #380. Can you review and let me know if that works in fish?
