When letConst transpilation is on, buble renames some variables, such as x->x$1. However, when shorthand properties are used, this causes the property key to change.
The appropriate fix is to make those properties no longer be shorthand, so something like { x : x$1 } is used.
This applies both to object literals and object destructuring patterns.
The destructuring and concise property transpilation options hide this bug, so this commit only improves the situation for use-cases where letConst transpilation is used without those options.
