Remove several domains from the HSTS preload list and remove an extra space.

videomail.io:

>         app.use(helmet.hsts({
>           maxAge:            108864000000, // Must be at least 18 weeks to be approved by Google
>           preload:           true
>         }))
> ```

> But now, I can't visit the local site with plain HTTP anymore. I need

tablotv.com:

bam.com.au: A mail subdomain hosted by a third-party does not support SSL.

logotype.se:
> The reason is that I do development, and for some subdomains I don't

I'd like to request a merge of 97d372c2bc6233832ee573db666579ea15209430 [1] and 253102d2f4b59a803816d2567233a5823ab5d782 [2] to Chrome 50.

These commits remove 5 sites from the HSTS preload list. Merging them to Chrome 50 will avoid an additional 6 weeks of breakage for them.

Although the commits contain a large diff of static data, this data is auto-generated using a process that has been working reliably for the last 2 years. Therefore, the merge is semantically equivalent to removing just those 5 sites from transport_security_state_static.json (and fixing a typo).
