Won't getBlockByNumber return a block object, not a number string like we probably expect here?

I believe it's impossible for blockGasLimit to ever be falsey, because it's given a default value of MIN_GAS_LIMIT_HEX

I've updated this to something simpler. We don't really need a strictly accurate blockGasLimit at this point.

Meanwhile, I think blockGasLimit can be falsey if the value passed to this function is defined but falsey.

e.g.

danjm@pop-os:~/kyokan/metamask-extension$ node
> const t = ({ a = 10, b }) => console.log(`${a} | ${b}`)
undefined
> t({ a: null, b: 5})
null | 5
undefined
> t({ a: '', b: 5})
 | 5
undefined
> t({ b: 5})
10 | 5
undefined

} catch (e) {
blockGasLimit = ARBITRARY_HIGH_BLOCK_GAS_LIMIT
}
}

paramsForGasEstimate.gas = ethUtil.addHexPrefix(multiplyCurrencies(blockGasLimit, 0.95, {
multiplicandBase: 16,
multiplierBase: 10,
roundDown: '0',
toNumericBase: 'hex',
}))
