fixed #478

[stroncium]

Essentially, going into link phase triggers additional cycle of interpolation(one outside of linking phase as usual, and one more inside) which leads to weird results.

The fix is pretty simple(and looking at the code, even thought of originally): switch mode to raw for the linking phase.

@kazupon Note:
Prior to this fix, 2 tests already failed on my setup:

• test/unit/datetime.test.js:50 - looks like timezone mismatch
• test/unit/number.test.js:58 - missing space

Not sure if those are known problems or if I should report them.

Oh, and for the context:

• link phase will treat raw by switching to string and disabling values for underlying phases
• render phase will obviously still run after linking phase, handling all the interpolations
• there are some more precise and invasive methods of fixing this, but I decided to stay on the side of least impact/changes, but if needed i can go deeper into it
• I added a test to ensure links to links still work properly

Good job! 👍
Thanks!
