Fix no suggestions in some inputs

Fix #101 (closed)

For some weird reason, when typing the first word for first time, no suggestions appear for english.

This has something to do with the function WordComposer. mWordComposer.getTypedWord() returns empty for the first word. I don't why this is happening for non-autocomplete inputs. But that's something to check later. Meanwhile this MR will work for Varnam.
