Convert api does not recognise IDT format during autodetection

[rrodionov91]

Steps to Reproduce

1. Send IDT string (f.e. /52MOErA/*/i2MOErC/*/32MOErT/) to convert api without "input_format": "chemical/x-idt" parameter

Expected behavior Indigo converts IDT string to KET format. In case if it is not possible to identify format (f.e. ACGT could be interpreted as IDT as well as Sequence or Fasta) - return error.

Actual behavior Indigo returns error:
