Change default scope delimiter to space

[driesvints]

I believe a space is the more sensible default as I've not seen too many examples using comma's.

See discussion here as well: laravel/passport#1008

Hi @driesvints, is this issue still on? I'll really love to contribute.
Thanks!

[driesvints]

@johnson-jnr yes :)

Probably best sent to master.

i would advise against this.
comma seems to be more frequent than space:
(excuse my bad shell scripting skills)

jim@jim:~/socialiteproviders/providers/src$ ack scopeSeparator | grep "' '" | wc -l
32
jim@jim:~/socialiteproviders/providers/src$ ack scopeSeparator | grep "'+'" | wc -l
3
jim@jim:~/socialiteproviders/providers/src$ ack scopeSeparator | grep "';'" | wc -l
1
jim@jim:~/socialiteproviders/providers/src$ ack scopeSeparator | grep "','" | wc -l
2
jim@jim:~/socialiteproviders/providers/src$ ls -l | wc -l
163

163-32-3-1 = 127

I'm gonna close this because this isn't much of an issue really. Might not be worth the breaking change.
