feat: remove status key in ApplicationError class, update meta key to unknown type

[karrui]

Problem

This PR removes the unused status class variable in ApplicationError class that may sometimes cause confusion when poring through logs for issues, since the default value is 500.

Also updates the meta key in ApplicationError to accept anything, since we may want to store more info from the creation of the error; e.g. storing original error that resulted in an ApplicationError being created for logging purposes.

Solution

Features:

• remove status key in ApplicationError class and all its usages
• update meta key in ApplicationError to unknown type

Sorry missed some tests; fixing tests, will reopen for review later!

Tested with putting another error inside meta, works fine (in JS Console)

let testErr = new ApplicationError('test message', {error: new Error('another error')})
console.dir(testErr)

output:

ApplicationError: test message
    at <anonymous>:1:15
message: "test message"
meta:
error: Error: another error at <anonymous>:1:60
message: "another error"
stack: "Error: another error↵    at <anonymous>:1:60"
__proto__: Object
__proto__: Object
name: "ApplicationError"
stack: "ApplicationError: test message↵    at <anonymous>:1:15"
__proto__: Error
