More reliable exception handling in Control.App Convert `App.Control.Exception` interface to an alias to `HasErr`. Probably `Exception` interface need to be deprecated or removed. Note similar problem exists with `PrimIO` calling `PrimIO, Exception`, also need to be fixed. Fix this scenario: ``` throwBoth : Has [Exception String, Exception Int] es => App es () throwOne : Has [Exception Int] es => App es Int throwOne {es} = handle {err = String} {e = es} throwBoth (\r => pure 1) (\e => pure 3) ``` With this commit it works, before this commit it failed with: ``` Error: While processing right hand side of throwOne. Can't find an implementation for Exception Int (String :: es). TestException.idr:8:48--8:57 | 8 | throwOne {es} = handle {err = String} {e = es} throwBoth (\r => pure 1) (\e => pure 3) | ^^^^^^^^^ ```
