Subject: [PATCH] fix(typings): allow bufferCreationInterval null for
 bufferTime (#3734)

* fix(typings): allow bufferCreationInterval null for bufferTime

The tests for bufferTime verifies that it is possible to set
bufferCreationInterval to null, but the typings did not allow it
when strictNullChecks were set to true.

Fixes #3728

* fix(typings): allow bufferCreationInterval undefined for bufferTime
