Assetpath attribute in dom-module has incorrect paths after vulcanize

[devAtPolydeals]

After Vulcanize, it adds the attribute 'assetpath' to . For me those values are all incorrect. Some have
<dom-module id="iron-pages" assetpath="../wer_components/iron-pages/">
others are
<dom-module id="iron-a11y-announcer" assetpath="../ower_components/iron-a11y-announcer/">

they all have to be bower_components and with path's that are dependant on the project.
