EffectBundle: Avoid possible out-of-bounds access

'preset' is allowed to be PRESET_CUSTOM, which is -1, when we
use it as an array index in an ALOGVV statement.  We change this
logic to just use 'name' directly.  While this risks a
truncation of the string, it avoids out-of-bounds and is
probably still sufficient for debugging.
