Agent wrongly identify stack traces line for Typescript

[IzioDev]

Describe the bug

The agent does capture stack trace but it wrongly claims that the line is 299 when it's 364 actually.

I first though it was a source map issue, but we do have the comment on the last line with a valid source map.

To Reproduce

Create a NestJS app, then install the apm agent and capture error in a error interceptor.

Expected behavior

We expect the stack trace to be good.

Environment (please complete the following information)

• OS: Linux
• Node.js version: 13.0
• APM Server version: 7.5.1 (we just updated it)
• Agent version: "elastic-apm-node": "^3.3.0"

How are you starting the agent? (please tick one of the boxes)

• [ ] Calling agent.start() directly (e.g. require('elastic-apm-node').start(...))

Additional context

Our stack trace (on stdout):

webhook_1          | GraphQLError: GraphQL Error
webhook_1          |     at GraphQLService.handleErrors (/usr/src/app/src/common/graphql/graphql.service.ts:14:21)
webhook_1          |     at BackendService.<anonymous> (/usr/src/app/src/backend/backend.service.ts:360:25)
webhook_1          |     at Generator.next (<anonymous>)
webhook_1          |     at fulfilled (/usr/src/app/src/backend/backend.service.ts:14:58)
webhook_1          |     at processTicksAndRejections (internal/process/task_queues.js:97:5) {

the stack trace (on kibana) :

Types are a nightmare on this project...

[IzioDev]

It's not types theirself the issue, it's the stack trace I have on Kibana APM. More specific, the line number, apm take the js line number and not the ts line number.
