bug: ionSpinner issues with utility color classes

[felquis]

Type: bug

Platform: all

This is "Kind of bug"

⚠️ This codepen is really annoying to see, everything is spinning http://codepen.io/felquis/pen/ZYmpPd

My notes are:

1 - The android spinner with spinner-clean is blue, but the others are black/gray, shouldn't it also be black/gray?

2 - All the spiral has with a black tail, there's some posts about it in the forum. But it's impracticable to use spiral with other colors because it just don't work as expected.

A bit related to #3077

Thanks.

The spinner-clean is something @adamdbradley intended. It's the default Android color, and "clean" is intended to be the spinner's default color. This will become more apparent as we add more complicated spinners. Right now, it's the odd one out.

The spiral tail needs to be fixed. Thanks
