imm32 [2/3]: Remove the unnecessary root_context cleanup code.

[Byeong-Sik Jeon]

1. When we think more deeply, this code unnecessary code.
   Wine check these variables when these is needed.
2. When we use the "SCIM"[1] (scim-anthy, scim-canna, ...) for Japanese
   character input, we can't get "result string". Because this code delete
   "result string". so, we can't input Japanese strings.
3. When we use the "nabi"[2] for Korean character input, if we press the
   korean/english toggle key in the composition state, "composition string"
   changed "result string". But this code delete the "result string", and
   we lost our input string. This is unwanted situation.
