Make handling of tuples more consistent in quasi-quotes
On one hand we know that q"($expr)" is the same as q"$expr". On the
other if we wrap it into a list and splice as q"(..$expr)" we get a
Tuple1 constructor call which is inconsistent.
This pull request fixes this inconsistency by making q"(..$expr)" being
equivalent q"(${expr.head})" for single-element list.
We also add support for matching of expressions as single-element tuples
(similarly to blocks) and remove liftables and unliftables for Tuple1
(which aren't clearly defined any longer due to q"(foo)" == q"foo"
invariant).
