Describe the bug

Servers.startOnPreferredPort() crashes when preferred port is taken

To Reproduce

  1. Use a port such as 3000
  2. Try to call Servers.startOnPreferredPort(3000) expecting it to find a new port automatically
  3. Observe that it crashes instead which is the exact opposite of what it's designed to do.

Expected behavior

It should return successfully with a random port allocation as the final resort fallback instead of crashing. That's the whole point of this particular implementation as used by the test at packages/cactus-test-api-client/src/test/typescript/integration/api-client-routing-node-to-node.test.ts

…edger-cacti#683

The code of the method was not waiting for a promise to resolve
which was masking the underlying exception that the code
was supposed to catch and examine in order to determine if
it should perform a fallback of binding to port zero or not.
Fixed it by making sure the initial try of the preferred port
allocation is awaited for so that the exception is thrown
where it is expected by the algorithm.
