fix(sandbox): serialize sandboxed job error

[LEI]

This change preserves the original error when throwing from a sandboxed job with a circular reference or I think a function in the object.

The TypeError is reproducible with worker threads off and a simple circular reference:

Worker failed TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'Object'
    --- property 'ref' closes the circle

The DataCloneError occurs with axios errors and useWorkerThreads: true, see this branch:

Worker failed DataCloneError: function transformRequest(data, headers) {
    const contentType = headers.getContentType() || '';
    const ha...<omitted>... } could not be cloned.

Initially attempted to check the value type ignoring "function" and serializing only "object", but using the stringify/parse method on the whole object seems more consistent and fixed all cases.
