Unecessary MainLog update

[raphidoc]

Describe the bug
When changing a project (i.e. a project is already open, and we open another one), OldMainLog is not updated (to the newly selected project) before

sear/R/mod_parse_data.R

Lines 102 to 130 in a0fbf7a

	UpdateMainLog <- observeEvent(
	{
	MTELog$ParsedData()
	},
	{
	# Create a Progress object
	progress <- shiny::Progress$new()
	progress$set(message = "MainLog check", value = 0)
	# Close the progress when this reactive exits (even if there's an error)
	on.exit(progress$close())
	OldMainLog <- MainLog()
	PrimMainLog <- MTELog$Apla() %>%
	rename(Lon = Lon_DD, Lat = Lat_DD)
	# TODO Need to figure out how to compute on BioSonic Load
	# | !is.null(BioSonic$BioSonic())
	if (nrow(OldMainLog) == nrow(PrimMainLog)) {
	message("MainLog up to date")
	progress$set(value = 1, detail = " up to date")
	} else {
	message("Updating MainLog")

is computed.
This lead to a useless recomputation of MainLog.

To Reproduce
Steps to reproduce the behavior:

1. Select a project with data already parsed (MainLog should be already computed)
2. Select another project with different data already parsed
3. MainLog() is updated because the Old (actually from the old project) and the New (newly selected project) don't have the same number of lines

Expected behaviour
MainLog to be the one of the newly selected project before UpdateMainLog be computed
