"no-floating-promises" does not report failure with .catch / .then(..., catch)

[oleg-codaio]

Bug Report

• TSLint version: 5.9.1
• TypeScript version: 2.8.3
• Running TSLint via: (pick one) CLI

TypeScript code being linted

    new Promise(resolve => resolve()).catch(e => {throw e;});

with tslint.json configuration:

{
  // ...
  "rules": {
    // ...
    "no-floating-promises": [true, "Bluebird"],
  }
}

Actual behavior

No error is reported.

Expected behavior

Would expect to be able to catch a floating promise via this rule, even if it requires a specific configuration parameter. This is because it's possible to throw errors in catch blocks, and not returning a floating promise in a chain can result in other bugs.

More context: basically would expect to be able to make the change in #3048 configurable.

☠️ TSLint's time has come! ☠️

TSLint is no longer accepting most feature requests per #4534. See typescript-eslint.io for the new, shiny way to lint your TypeScript code with ESLint. ✨

It was a pleasure open sourcing with you all!
