MTEncDecModel translate drops text, when input text is large
**Describe the bug**

Is there a limit to the maximal text input length when calling `MTEncDecModel.translate()`? I mean the length of individual strings or size of List. Is it model config dependant? E.g. is it determined by `max_sequence_length`? If so, is this the number of tokens after tokenisation with `encoder_tokenizer` or the length of the string (chars with spaces)? I am asking this as I have noticed that when passing large text blocks (e.g. 3000 chars with spaces), the translation does work, but a large portion of input text is dropped.

**Steps/Code to reproduce bug**

Run `MTEncDecModel.translate` with list containing one large block of text.

**Expected behavior**

The entire input be translated, or a warning printed out that the output is/will be truncated.
