Loader is not visible if color is not specified

What package has an issue

@mantine/core

Describe the bug

In Mantine v 5.1.0, Loader component is not visible if the color prop is not provided, it should fallback to the theme's primary color. This affects LoadingOverlay too as it uses Loader internally. See codesandbox below for an example.

What version of @mantine/hooks page do you have in package.json?

5.1.0

If possible, please include a link to a codesandbox with the reproduced problem

Do you know how to fix the issue

No

Are you willing to participate in fixing this issue and create a pull request with the fix

No

Possible fix

Could be fixed by using primaryFallback: true in Loader.tsx#L58.

This possibly affected other components as there are similar changes to lines that used color || theme.primaryColor in commit c9b5e7e.
