Release v0.15.1

Improvements

• This is the first release supporting OTP 26. Unfortunately due to bugs in OTP only 26.0.2+ is supported. See 886 and 923 for details

Fixes

• Fixed crash when handling workspace/didChangeWatchedFiles when project_dir not yet set
• ExUnit test tracer is now under build lock. This should fix crashes due tu race conditions
• Fixed completion of remote calls matching locals without parens (e.g. Map.drop when drop is local without parens from ecto_sql) Milo Lee
