Plugin causes a crash in the debugger when exiting

[prolium]

If the search dialog of the plugin is initiated (opened at least once), the debugger will always crash when exiting it.

Steps to reproduce:

1. Open x32dbg.exe.
2. Select Plugins -> ClawSearch -> Open search dialog.
3. (Optional) You may close the search dialog if you want, it won't matter.
4. Try to close the debugger, it'll crash and generate a minidump file.

• If you skipped step 2, the debugger won't crash.
• On older versions of the debugger (ex: snapshot_2017-09-12_00-45) this doesn't happen.
• Building the project with Visual Studio 2013 won't matter.

• Debugger version: clean version of snapshot_2017-10-24_01-20
• Plugin version: ClawSearch_2017_10_24
• OS: Windows 10 x64 v1607 (build 14393)
