specific alias not created in capsule

[GiladShoham]

Describe the bug

I'm trying to build a component from ngx-bootstrap, but the capsule is missing one alias under ngx-bootstrap.

This looks like a bug in the dep resolution since the bit show datepicker -j doesn't show it as "isCustomResolveUsed": true,

Steps to Reproduce

1. clone ngx-bootstrap
2. use the following bitmap
   bitmap.txt
3. bit build datepicker
4. look into the capsule under ngx-bootstrap it should contain utils folder required by few files in the component (like: src/datepicker/daypicker.component.ts)

Expected Behavior

utils folder should be created

Specifications

• Bit version: master
• Node version: 10.16.0
• Bit compiler (include version): custom ng compiler v0.0.18
