Paintroid-638 : Add a placeholder name when saving

Description
If the user saves a project there should be a placeholder in image name like in Piantroid Android.
For the "Save image" dialog, the placeholder should be "image[number]" with the number being the next available number not yet taken in the files.
If I create my first image it should say "image1", when I save this and start a new image it should say "image2".

Same for the projects, here the placeholder should be "project[number]"

@juliajulie95 I apologize for the inconvenience. I have identified the issue and am currently implementing a fix. I added print statements for my self-debugging. I will fix ASAP and commit the changes.

@juliajulie95 There is a problem in the unit test case
final textFormField = find.widgetWithText(TextFormField, 'Project name');
expect(textFormField, findsOneWidget);
this line in landing_page_test.dart is checking for text Project name but finds autosuggested names like Project1, Project2 etc, which is placeholder names. widgetWithText is very strict with comparing text so a text regex is not a solution. So can I edit this line in this unit test?

@vishad-tyagi You can definitely change a test if the functionality changed

[vishad-tyagi]

@juliajulie95 ok I will make changes in test case and commit them ASAP

[vishad-tyagi]

@juliajulie95 Kindly check once more, all test cases are passed on my local machine. I have removed the self-debugging print statements
