Improve Error Messages around Fee Estimation

[cipherzzz]

Problem

I attempted to deploy a contract and received the following message:

Error estimating transaction fee. Response 400: Bad Request. Attempted to fetch http://localhost:3999/v2/fees/transaction and failed with the message: ""

Solution

It would be great for the API to send a better description than an empty string

Underlying Issue

The actual issue was that my contract name was too long

reference:

stacks.js/packages/transactions/src/builders.ts

Line 192 in bb0b85d

export async function estimateTransaction(

Hmm, yeah we should give better error messages. I'll check if the API is returning actual information.
