Fix Type Tool Cursor Jumping

[shun-iwasawa]

This PR fixes a following problem of Type Tool when inputting text with non-Latin alphabets such as Japanese.

• While typing the text, pressing the Shift key unexpectedly moves the cursor to the beginning.

In the type tool QInputMethodEvent is used only when typing non-latin alphabets. TypeTool::m_preeditRange specifies the location where the text to be inserted.
Pressing the Shift key reset the location (at line 1534) before going out of the function, which was the cause of the problem.

@shun-iwasawa All appears to be in order.
I'm not sure how thoroughly I can test non-latin alphabets without adjusting my operating system to fully test however. I can press into that if necessary.
Otherwise, recommend merging this PR yourself at your own discretion.
