baseUrl is not taken into consideration when performing path resolution

[jdalrymple]

If the baseUrl is anything but the root, the resulting paths are incorrect. Simple fix would be to add the base url path between the absolute path and the alias paths i.e:

baseUrl: ./src
alias: '@components/' : './components/'

resulting path = .../absolute path/{baseUrl}/{aliasPath} = .../absolute path/src/components/

Right now, the resulting path is '.../absolute path/components'
