Hack workaround for multiple-extend about fluent-json-schema

[dfee]

Also, it's unclear what this means:

I decided to block all the method after .extend to avoid incorrect usage.

from #69 (comment)

What is the incorrect usage?

[aboutlo]

const base = S.object()
  .extend(SCHEMA_BASE)
  .prop(
    'reason',
    S.string()
      .minLength(1)
  )

the fact that you first extend then you add the prop it could easily create confusion.

On the other hand, this is a fair case

S.object().extend(S.object()).extend(S.object())

Looks good! Any plan on merge / release?
