update fillSlot and freeSlot state requirements
...
`fillSlot` and `freeSlot` must both be in a state of New or Started and not Cancelled (Finished to be added later).
Update tests to support the above.

slash first then check collateral threshold
...
Once a proof is marked as missing, if that missing proof is enough to slash a host, first slash the host, then check the hosts balance. If the balance has dropped below the minimum allowable collateral threshold, then remove them from the slot.

[marketplace] update state getter
...
Update `Marketplace.state` getter to to take `isCancelled` into account. This state can then be used internally and externally.
Add checks to `proofEnd`, `isProofRequired`, `willProofBeRequired`, and `getChallenge` that understands if the request is in a state to accept proofs. If not, return other values.
Add `slotMustAcceptProofs` modifier, originally introduced in a later PR, which requires the request to be in state of the request accepting proofs.
Add tests for all the above.
