quotedblbase shows both quote signs google/fonts#129

Apparently, quotedblbase consisted already of two comma components but
they were on the same spot.

NOTE: I replaced the comma components in quotedblbase and in quotesinglbase
with components of quoteright, because the bold comma is heavier than the
bold quoteright and that caused an imbalance between the base-line quotes
and the upper quotes.

Code looks good. I don't know how to check it visually.

On the "View changes" site you can click "View" and there "Download" to download my Poppins.glyphs file. This is the download link then: https://github.com/graphicore/poppins/raw/d5d48759fdb83fcb423109ef2b396ce447c524d9/masters/Poppins.glyphs
Best use a right click and choose "Save Link As…" otherwise the file will probably open in your Browser as a text file.

I'm new to fonts. I know how to download .glyphs file, but I don't know how to "test it visually" - I mean to see how it is rendered i.e. in browser.

Yesterday I was writing review for some new web page using Poppins font and I found bug. Then I found your fix. Then I thought that it would be fun to fix Poppins font instead of changing Poppins font to different font.

EDIT: OK now I know that I should buy a Mac probably. Also I have errors when trying to run build.py . It looks that my firs attempt to Type Design fails.
