Studio.new() doubles tilde when path starts with ~/

[williamsharkey]

Bug Description

Studio.new('~/code-metrics.js') creates a file at ~/~/code-metrics.js instead of ~/code-metrics.js.

Steps to Reproduce

Studio.new('~/myfile.js')
// Returns: {success: true, path: "~/~/myfile.js"}

Expected Behavior

Studio.new('~/myfile.js')
// Returns: {success: true, path: "~/myfile.js"}

Current Workaround

Studio.new('myfile.js')  // Without ~/ prefix
// Returns: {success: true, path: "~/myfile.js"}

Root Cause

Likely the new() function prepends ~/ unconditionally without checking if the path already starts with it.
