* test(tab-bar): update tests to remove layout
* fix(segment): set the colors in the parent segment
but use them in the child segment button
This allows the user to customize all of the segment buttons from segment, while still allowing the `color` property to take precedence, and they can also edit the segment button colors directly if desired.
This actually fixes some bugs surrounding colors and allows customization for a segment inside of a toolbar.

BREAKING CHANGES
Segment Button now requires the text to be wrapped in an `ion-label` element for improved styling.
*Old usage:*
```html
<ion-segment-button>
Item One
</ion-segment-button>
```
*New usage:*
```html
<ion-segment-button>
<ion-label>Item One</ion-label>
</ion-segment-button>
```
Note: this will not technically break your app, but the styles may look wrong.
