Fix load issue when deleting files

[joelim-work]

• Fixes Redraw window after delete #792

When deleting files, reloading the directory is already handled by the thread performing the actual deletion:

lf/nav.go

Lines 1475 to 1484 in 027538e

	if gSingleMode {
	nav.renew()
	app.ui.loadFile(app, true)
	} else {
	if err := remote("send load"); err != nil {
	errCount++
	echo.args[0] = fmt.Sprintf("[%d] %s", errCount, err)
	app.ui.exprChan <- echo
	}
	}

The reload is also done called by the main thread - I don't know why that code exists, but it appears to be the root cause of #792. The actual analysis involved is quite complex so I won't repeat it here, but see #792 (comment) for more details.

@joelim-work Thank you very much for investigating this issue. I have tried the patch and it fixes the issue for me. I'm not sure why there was an extra loading there either.
